I have a table in a data grid the columns are bound to the columns...
SQFT QTY WIDTH LENGTH
i also have added into the datagrid an unbound column called Yeild%.what i'm trying to do is the following formula
SQFT / (QTY * (width * length / 144) and have the result return the answer in the unbound yield column for that row represented as a percentage
So if SQFT = 178 QTY = 2 Width = 144 Length = 102 answer would be 0.87 (rounded)
so this would be 87%

I'm developing a data logging application using VB for the actual logging to a MySQL database. I'm reading a value from a device and then running an insert query every minute. This is great but if the value doesnt change all day then my records are going to all be the same. I'd like to try and calculate the percentage of change on the value and only run the insert query if the percentage of change is greater than, say 5%.

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.

View 3 RepliesI've setup a listview with two columns. Both have a fixed width which totals the width of the control (to fill the control fully and not display a horizontal bar)This works fine as long as the form does not change, anything such as a font change on the system will cause the list view to look off alignment.LV2.jpg shows it in the designer, LV.jpg shows the same listview with a different font.Is there an easy method to fix the position or auto size the last column to the edge of the control?
